Razer Stargazer Webcam (U.S. retailer-reported model RZ20-01800100-R3U1) review

Razer Stargazer, support model RZ20-01800, is a RealSense desktop webcam from a period when 720p at 60 frames per second was a distinguishing capture mode. Best Buy's U.S. page identifies the black webcam as MPN RZ20-01800100-R3U1, item 5614200; the U.S. model suffix is retailer-reported, not a Razer-hosted cross-reference. Best Buy said its listing was no longer available new when checked, which describes that one page rather than the whole market. Razer's historical announcement and current support result identify the camera family. This is a source-based assessment: the camera was not handled or tested, and no image-quality, tracking or microphone measurements are claimed.

Two different video choices, not one combined maximum

Razer's 2016 U.S. announcement specifies Full HD at 30 fps and 720p at 60 fps. Its model-specific support page gives the same key boundary another way: 1080p capture resolution, with 60 fps available at 720p. The higher frame rate therefore comes with lower resolution; it is not a 1080p60 camera. Nothing in the reviewed sources establishes a 4K webcam mode. Razer's support guidance names OBS and XSplit for selecting 720p60, while separately stating that conferencing and broadcast applications recognize the device as a standard 2D webcam. That general recognition statement is not a guarantee that every current operating system or app will expose the same settings.

Check the host before considering the camera

The bigger constraint is the computer. Razer's product announcement says Windows 10 only, a sixth-generation Intel Core processor and USB 3.0 connectivity; the support table specifies USB 3.0 only. The English Master Guide also lists a free USB 3.0 port, 4 GB memory, 8 GB free disk space, Intel HD graphics, DirectX 9.0 and an internet connection, and warns that some applications need more. These are legacy system instructions, not a current compatibility matrix. Do not infer that a newer Windows, Mac, Linux or ChromeOS machine will work simply because an app recognizes USB webcams in general. If the named generation of Windows and processor is not part of the plan, this model is a poor fit on the evidence reviewed here.

RealSense is the distinctive part, with a software caveat

The front assembly combines a color sensor, infrared sensor and infrared laser projector, along with a dual-array microphone. Razer's announcement describes Intel RealSense SR300 depth features such as dynamic background removal, 3D scanning and facial or gesture recognition. Its support instructions point users toward an Intel RealSense Depth Camera Manager and a list of supported applications. That makes Stargazer more than a basic call camera on paper, but it also makes the older software stack central to the special functions. The sources reviewed do not establish which of those older applications and drivers can still be installed or work on a particular present-day computer. Treat the depth features as historical manufacturer-described capabilities, not an assured ready-to-run workflow today.

Audio hardware is listed; sound quality is not

Razer specifies an automatic-noise-cancelling dual-array microphone. That is useful if a built-in camera mic is a requirement, and it is why Stargazer enters the earlier-inclusive microphone comparison. A specification does not show how voices will sound across a desk, in a reflective room or beside keyboard noise. Razer's own announcement points streamers toward its Seiren or Seiren Pro microphone when the best broadcast audio is wanted. If voice quality matters more than having a mic in the camera, budget for a separate audio path and check the input that the chosen conferencing or streaming program actually selects.

Mounting and package details need an exact-unit check

The English Master Guide describes a flexible clip for a laptop, desktop monitor or television and a mounting hole for tripod placement; it explicitly notes that the tripod is not included in its setup instructions. Its layout diagram labels a 2.5 m (98.5 in) USB 3.0 cable. The model-guide package list names the webcam, cable and Important Product Information Guide, but that list cannot prove what survives in a particular used or reseller unit. Before considering one, confirm the exact model label, cable, clip, physical condition, return terms and seller. Do not assume a missing tripod is a defect or that a marketplace bundle contains original Razer accessories.

Unknowns that should remain unknown

The exact-model support table and guide reviewed here do not specify autofocus, fixed focus, focus range, an integrated physical shutter or TAA compliance. Stargazer therefore does not qualify for a strict focus, physical-cover or TAA requirement on this record. Its official support result gives dimensions of 92 × 128.6 × 28 mm and weight of 194 g, useful for checking shelf or monitor clearance, but those dimensions do not substitute for inspecting the mount and cabling on an exact unit. The official image shows the camera body rather than the retail box, condition or included accessories.

Bottom line

Stargazer is a specialist earlier webcam to compare only if its particular host requirements, USB 3.0 path and mode tradeoff make sense: 1080p30 for detail or 720p60 for a higher frame rate, not both at Full HD. Its built-in dual-array mic and RealSense depth sensors distinguish the design, but neither audio quality nor current driver/app behavior has been independently established. A buyer should verify the exact historical part and unit carefully, and should not treat Razer's older RealSense feature list as proof of a supported modern workflow.
